Re: [avr-gcc-list] avrxmega7 device-not-found

[Adisak Anusornsrirung]

This because you include file avr/io.h and in the file avr/io.h is not have your device in the list.

 

This is some part in avr/io.h

 

#elif defined (__AVR_ATxmega256A3__)

#  include <avr/iox256a3.h>

#elif defined (__AVR_ATxmega256A3B__)

#  include <avr/iox256a3b.h>

#elif defined (__AVR_ATxmega256D3__)

#  include <avr/iox256d3.h>

 

Can you see the line #elif defined (__AVR_ATxmega256A3B__) in your avr/io.h file? If you can not found this line the compiler will show "device type not defined", So, you will need to find new(or may be old) version of your avr-gcc compiler.

 

simply use avr-gcc -mmcu=atxmega256a3u for you device.

Yep, I can understand what the issue is; it is just that I don't know how to resolve it.

The point is, using "avr-gcc --target-help" lists "avrxmega6" as one of the supported targets, then I fail to understand why the "device not found" error is emitted.

More strangely, things work fine for some targets ("atmega8" for example), but not for others ("avrxmega6" for example).

So, I will be grateful if someone could explicitly tell me what to do to get things working for "avrxmega6" target.

Thanks and Regards,

Ajay

you need to add your mcu type in ave/io.h file.

"avrxmega6" does not work either :(

Clearly either I am missing something, or something is really screwed up :-\

The avr libc user manual shows that part under supported devices. Have you tried it?

Senthil,

(I am just a newest newbie, but,) Assuming your hypothesis is correct, what should I pass to compile the code on http://www.atmel.com/tools/XMEGA-A3BUXPLAINED.aspx, using Atmel ATxmega256A3BU microcontroller?
